Same happened for me, mate. One thing I've learned is that DFR aren't really on your side, so be persistent with them, they have a lot to do and can takes ages to do things.
I passed my assessment and it was a solid 3 weeks with no contact at all so I called them every day for a week (for some reason nobody at the medical centre ever picked up the phone) and finally got the info I needed. Then they'll just send through all the info you need for your dental, optometry etc...
You have to do more medical testing after flight screening so have fun with that
